Ah, that's very useful information. I actually maintain multiple NSTextStorage instances, one for each file that's being managed, and swap those in and out by doing setTextView on the storage instance. So is this somehow bypassing the chain of notifications that tells NSTextFinder that the string changed? Any way around that?
